Image to text

Image to text OCR that copies the words out of a photo, screenshot or scan. Recognition runs in this tab with the open-source Tesseract engine. Every word is boxed on the image and coloured by how sure the engine was, so you know which ones to check.

Words to check

Below 70% confidence, lowest first. Numbers and names are worth a second look even when confident.

Clean up the image, then compare

Tesseract reads dark text on a light, even background best. Turn on any of these, run again, and each run is added to the table so you can see whether it actually helped this image.

check_box_outline_blankGreyscaleRemoves colour so coloured paper or tinted photos don’t confuse the binariser.
check_box_outline_blankThreshold (Otsu)Turns every pixel black or white at the level that best splits ink from paper. Helps faded or uneven scans.
check_box_outline_blankEnlarge 2×Small text gets more pixels per letter. Helps screenshots and distant photos; slower to read.
